The Siberian ring source of photons (SKIF) is a new 3 GeV
fourth-generation synchrotron light source being developed by the
Budker Institute of Nuclear Physics (BINP). A beam loss monitoring
system is necessary to ensure its reliable commissioning and
operation. Two types of beam loss monitors will be installed in the
SKIF: 5 fiber-based Cherenkov beam loss monitors (CBLMs) for the
linac and transfer lines and 128 scintillator-based beam loss
monitors (SBLMs) for the storage ring. Sophisticated electronic
equipment is employed to use these monitors in different modes of
SKIF operation. The paper describes the design of the SKIF beam loss
monitoring system based on numerical simulations and experimental
studies.
